RT‐PCR was applied for detecting the expression of MALAT1 in tumor tissues and para‐cancerous tissues of LSCC patients, which demonstrated that the expression of MALAT1 in LSCC tissues (ie 9.64 ± 0.82) was overtly higher than that in adjacent normal tissues (ie 3.24 ± 1.55) (P < .05) (Figure 1A). This evidence concerns the gene MALAT1 and neoplasm.
